IMPROVEMENT IN SASH-FAS'TENERS.

Specification forming part of Letters Patent No. 199,916, dated February5, 1878; application filed June 30, 1877.`

To all 'whom it may concern:

Be it known that I, ABRAHAM W. LozIER, of New York city, in the countyand State of New York, have invented a new and Improved Window-SashFastener, of which the following is a specication:

Figures 1 and 2 represent top views, partly in section, of my improvedwindow-sash fastener, showing it in different positions. Fig. 3 is across-section on the line c c of Fig. l. Fig. 4 is a top view of thesame on a reduced scale, showing it attached to a window-sash. Fig. 5 isa side view thereof, showing it also attached to a window-sash. Fig. 6is a crosssection on the line k k, Fig. 2.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention relates to a new device for locking window-sashes in anydesired position, and is intended to be used at the side of the sash,either alone or in connection with the ordinary center sash-fasteners;but 'my invention is also applicable as a center sash-fastener on sasheswhich are divided in the middle.

My invention consists of the peculiar construction and novel combinationand arrangement of parts, hereinafter more fully described and claimed.

The letter A represents the base-plate of my improved sash-fastener.From it projects a box, -B, which is, or can be, covered on top, asindicated in Figs. 3- and 6. Within this box, which is open at one end,is pivoted, by a pin, c, a lever, O, which extends through said open endof the box, and which, when the plate A is screwed upon the top rail ofthe lower sash, faces the side rail, or any other upright rail of .theupper sash, as indicated in Fig. 4. That portion of the lever C whichfaces the upper sash may be lined with rubber, as indicated at b, inFigs. l and 2. Through the other end of the box B is inserted a slidingbolt, D, which has at its outer end a handle, d, and at the other end acam or eccentric, e. fis a spring which bears against the lever C, and

tends to throw the same off the upper sash, as

in Fig. l2, whenever the bolt D is drawn out,

.asis also shown in Fig. 2. That portion of the lever C which faces thecam e widens toward its outer free end, so as to present a gradualwedge-surface to the advancing movement of the cam e.

When the sashes are to be locked, the bolt D is pushed into the box B,as far as it will easily go, against the wedge-shaped edge of the leverC, and then turned to causethe eccentric e to crowd the lever C firmlyagainst the upright face of the upper sash, as indicated in Fig. l. g

The lever C has an aperture, g, through it, which aperture, when thelever is in the position shown in Fig. 2, is directly above one of thescrew-holes of the plate A, to allow the convenient application of thescrew by which the plate is fastened to the lower sash.

The bolt D has a projecting rib, h, along part of its length, which ribts in-to a corresponding groove at the outer end of the box B, andprevents the bolt from being turned unless it is first pushed intothebox.

To the upright of the upper sash I prefer to fasten a plate, E, whichhas two or more projecting lugs, z' i. Under either of these lugs thelever C can be locked, and I am thus enabled to lock the sash in what istermed the ventilating position-that is to say, when the upper sash ispartly lowered.

I claim as my invention- 1. The combination of the plate A and box Bwith the vibrating lever C, and with the sliding bolt D, which moves inan oblique direction against the exposed face of the lever,substantially as herein shown and described.

2. rlhe bolt D, made with the -eccentric e, and with the projecting ribh, and combined with the box B and with the lever C, to operatesubstantially as herein shown and de scribed.
